Are you asking whether you can tell which application (IP address) has the queue open and is consuming messages ? Or are you asking whether, long after a message has been taken off a queue, whether you can tell which client took it?
The answer to the first one is 'yes'. The answer to the second one is 'no', unless you want to do an awful lot of logging of data.
If you describe your question a little more specifically I'm sure we can give you more details on the answer,
Cheers,
Paul.

Well, in the base queue manager the answer is no. IBM MQ can process tens of thousands of messages a second. If you wanted to log the getter of every single message then you would be talking a lot of data and it would potentially have a significant impact of performance.
Having said that I don't doubt there are 3rd party vendor products which will long this kind of information for you by installing exits in various places or you yourself could write an API exit which would intercept this information and squirrel it away somewhere.
Cheers,
Paul.

Why would more than one application be able to get messages from a single queue?
Why wouldn't the application itself log when it read a specific message and some minor information about that message?
As mentioned, MQ doesn't log this information in a historical record for you.
If you fundamentally require this information available at all times, you must be prepared for a large data store and a hit on the performance of MQ. |

Have you been asked to prove that a message was (or was not) processed?

Multiple instances of the same application code?

You could use accounting statistics, if you also care about recording this for the near future. That is what I use when I want to monitor a queue manager for say a week and see what clients are accessing the queue manager.
